Chapter 6: Arrays and Strings in Java Chapter 6: Arrays and Strings in Java Welcome to Chapter 6 of our Java Programming Course! In this chapter, we'll explore two of the most fundamental data structures in Java: Arrays and Strings . 🔹 What is an Array in Java? An Array is a collection of elements, all of the same type, stored in contiguous memory locations. It allows you to store multiple values in a single variable. 👉 Declaration and Initialization int[] numbers = new int[5]; // Declaration numbers[0] = 10; numbers[1] = 20; // ... up to index 4 👉 Shortcut Initialization int[] numbers = {10, 20, 30, 40, 50}; 👉 Accessing Array Elements System.out.println(numbers[2]); // Output: 30 👉 Array Length System.out.println("Length: " + numbers.length); 🔹 Multidimensional Arrays int[][] matrix = { {1, 2, 3}, {4, 5, 6} }; 🔹 Looping Through Arrays for (int i = 0; i < numbers.length; i++) { System.out.println(numbers[i]); ...
